Many equipment brokers and resellers install third party motors, controllers and other components into their Semitool semiconductor equipment. The frequent result: poorly performing tools that are hard to maintain, troubleshoot and support, adding hidden costs to your purchase. Rhetech remanufactures Semitool equipment using only OEM parts, original software and documentation. To minimize particulates, rotors and bowls are electropolished to new tool specifications. Rhetech restored tools are functionally equivalent to new.
